Display Panel Segmentation for Scanning Line Charging Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display device driving methods fail to achieve increased panel size or resolution due to decreased charging time for scanning lines and signal delay caused by impedance and capacitance as panel sizes grow.
Innovation Solution
A display device comprising a display panel with multiple areas and a driving chip that controls adjacent display areas to scan towards or away from each other, allowing simultaneous driving signal input to scanning lines, thereby increasing charging time and improving uniformity and resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the panel size and resolution are increased, then the display quality is improved, but the charging time for scanning lines decreases and signal delay increases
Solution Approach 1:
The display panel is divided into multiple independent scanning regions, each with its own scanning lines that can be charged simultaneously. This segmentation allows parallel charging operations, effectively increasing the total charging time available for each scanning line while maintaining high resolution and large panel size.
2Area of stationary object
If the panel size is increased, then the display area is enlarged, but the signal delay increases due to impedance and capacitance
Solution Approach 1:
The display panel is divided into multiple independent scanning regions with separate scanning lines for each region. This segmentation reduces the length of individual scanning lines, thereby reducing the impedance and capacitance effects that cause signal delay, while still achieving a large overall display area through the combination of multiple regions.
Solution Approach 2:
Instead of using a single set of scanning lines that span the entire large panel, the invention introduces multiple scanning regions with their own scanning lines. This dimensional approach to signal distribution reduces the effective length of signal paths, minimizing RC delay effects while maintaining the large display area.
3Manufacturing precision
If more scanning lines are added to increase resolution, then the display quality is improved, but the charging time for each scanning line decreases
Solution Approach 1:
The display panel is divided into multiple independent scanning regions, each with its own set of scanning lines. This segmentation allows simultaneous charging of scanning lines across different regions, effectively parallelizing the charging process. As a result, even though each region has high resolution with multiple scanning lines, the charging time per scanning line is increased because charging occurs in parallel across regions rather than sequentially.

AI summary
A display device is disclosed. The display device includes a display panel and a driving chip. The display panel includes at least a first display area and a second display area arranged side by side along a first direction. In the present application, by controlling any two adjacent display areas to scan toward each other or to scan away from each other, at least one scanning lines in the first display area and at least one scanning lines in the second display area simultaneously receive driving signals input from the driving chip.
